Using block content to disable scripts

Thursday, 15. January 2009, 23:07:02

This is more of a working hack because block content works with images etc.
I made changes to the contentblock.css file so I could include my own "bar" with script images at the top of the page.

And I made a userjs to list the scripts faked as images in that bar, so when clicking them, opera's block content feature actually blocks it.

contentblock.css

Scriptblock.js

By default, the bar is always on, as you can hover over the items to see their addresses, however its not possible for me to show the addresses before blocking them in blocked content(css hover doesn't work, neither does mouseoever/out events). So be careful what you block.

If you want the bar hidden by default, replace line 7, shown below:

scriptslist.style='display:block;position:fixed;top:0;left:0;max-height:62px;overflow:auto;background-color:beige;border:1px dotted black;width:100%;font-size:10px !important;z-index:9999 !important';


with this:

scriptslist.style='display:none;position:fixed;top:0;left:0;max-height:62px;overflow:auto;background-color:beige;border:1px dotted black;width:100%;font-size:10px !important;z-index:9999 !important';


Enjoy :smile:

EDIT: Changed it so the image alt is shown, and if there are many scripts, there is a scroll list.

Change address in almost any IE window(anything that uses IE's engine)This is why there should be no war.

Interesting, thanks.

Add address in alt? It's work.

var scriptz=[];
opera.addEventListener('BeforeExternalScript',

Hmm.. Why not simple «document.getElementsByTagName('script')»?

@lex,no hover effects work at all in block content mode, not even mouseover.
Also getting scripts from DOM doesn't always work, eg whole page could be rewritten without script tags.

Ok, I've decided to do it your way instead, and changed font size to 10px to fit more scripts in, and added a scroll if there are more scripts. I don't think there is a way to detect is something is blocked during block content mode though.

would this include css hover effects?
.stuff:hover:before { content: attr(alt) }

BeforeExternalScript doesn't fire for blocked elements... if i remember correctly. That would explain the counts being off.

Scriptblock.js breaks http://maps.google.com (sample).

Do these script work as your BlockIt.
Do I have to download contentblock.css & Scriptblock.js together?
If I have to use 2 of them, how can I install contentblock.css?


Simon Houston 21. August 2009, 17:36

You save the file over the current one, most likely in your profile > styles folder, or opera folder > styles

Thanks for your direction.

This script is very cool! Some flash are also advertisements. Could the bar shows the link to flash, too?
